How to alternate between login screen types in Windows 7?

Question

When already at the default login screen in Windows 7 where you click on an icon to select a user, is there a way to switch to the mode where you enter both a username and a password?

In Windows XP, this was done by simply pressing Ctrl+Alt+Del twice.

I know that you can change the default to the mode where you enter both a username and password, by enabling the group policy "Do not display last user name". That is not the point of the question!

Answer 1

I don't think that's possible.

In Windows 7 you you either enable or disable the Secure Log On, as explained here, but you cannot switch between them by pressing Ctrl+Alt+Del,
